Liberal arts troll reporting. Starting my prereqs for a masters in CS this summer. It'll take me quite a bit longer to complete than someone who started with a BS in CS (basically I'm taking enough undergrad courses to fill several semesters, before even getting to MS work). However I was a developer for several years before this leap, and I feel pretty comfy with math things. Also working on reproducing papers to develop chops, in my spare time so my dev skills don't go to nil. Excites me since I've always wanted to grow to this level as a dev, I just never had an excuse to go for the CS degree till ML came along.
